<p>PROBLEM TO BE SOLVED: To reliably judge the interruption of writing when writing is interrupted caused by abnormalities of a power source during writing of a plurality of traveling data. SOLUTION: When the judgement that recording of the traveling data of a vehicle is required is performed (S30), a memory area for recording this time traveling data is determined from the memory areas of an EEPROM, ID numbers to be recorded in a first section S1 and a last section S3 of the determined memory area is determined (S40), the ID number is written (S50) in the first section S1 of the memory area by overwriting, respective data from the first traveling data to the last traveling data are sequentially written (S60 to 80) into a section S2 of the memory area, and the ID number is written (S90) in the last section 33 of the memory area.</p> |
